Most definitely a treasure Documentary on a much beloved heavy Rock N Roller Master-Musician Drummer Randy Castillo: won't ever forget setting "eyes" on him in OZZY OSBOURNE Band: the Ultimate Sin Classic album and music video's (incredible OZZY line-up legends there, too: awesome live and in Studio pix of him and Rebel band-mate Jake E. Lee!!) And the Ultimate Sin 1984 Tour are Solid Gold treasures!! Mega kick-buns) in the early-mid 1980's. He Randy CASTILLO was/is and will forever be an AMAZING Drummer (he and Tommy Aldridge kicked-mega buns playing Drums in Ozzy Band...'what energy and Creativity. All the former OZZY band-mates possessed)...'I love his style and his Classic Porcupine hair-do. Plus, what a handsome "gorgeous" Drummer man he was: very, very talented/Gifted and "yes" he is truly missed. Rest in sweet Harmony Mr. Castillo.
